It is frequently desirable' to leave the Windows of a house in partlyopened position for ventilation or the like', and to a means forloclr-`r y ing the windowsin this partly opened` position,

and in order to accomplish this-result, I have f provided a devicewhichmaybe mounted uplone of the window sashes and which will have,a..por

tion extending into the path of, movementr of the other window rsash toabut therewith, and

prevent urtherfopening' of the window and'fin order that this device.may beV moved from such locking position without thecompleteremoval ofthedevicefrom'the sash, I have hinged the abutment part to abase portionthereof `so that it may be swung from abuttingg or noperative positiontor inoperative position, ;and vthe foilowingis" a detailed descriptionof thepresent embodiment of this invention,'illustrating the preierredmeans by which Athese advantageous results may be ac complished.` u' .in

With reierence to the drawing,4 ylode'signates a base plate Vormemberlprovidedfwith bevelled edges 11 and 12 to provide a betterappearance @and `a base lessliable to yabrade; parts coming` in Contacttherewith. The base is provided with hinge lugsr 13 and 1li, between'whichthere is positioned the bearing portion 15 ofy the mounting member16 and through which hingelug'sfand bearingportiona pin` 17 Iextendstolhingedl'trv mount'thesetwo: niembers'- together. v A recessf 18 V isprovidedinthe faceof the base member ofa depth substantialh7 the`thickness of the mount-f ing member 16 toreceive this mounting memberopenings register when the mounting member-is a said recess and whichopenings threadedly re-' ceive the stud portion 21 of the abutmentmember i 22 which is provided with a handleA portion 23 having recesses24 therein to provide a better gripping surface formanual rotation.

In, use, the base member 10 is mounted upon the upper sash 2 5 of awindow by' suitable screws extending through openings therein, whichsash carries a pane of the'glass 26, the location being about six inchesabove the joint of the sashes when in closed position; the window sothat the sashesmay be opened about six inches, the abutment member 22 isWhen I desire tolock Y.

located in the position illustrated'in Fig. i1, with the shank portion21thereof engaging both of the desiredposition to obstruct the passageof the sash 27, by reason of the upper horizontal bar 28thereof,.engaging the abutment member l22 as illustrated in Fig. 3. Thisposition of the device permits the limited opening of the window, and asit is necessary to rotate the round abutment to unlock the same, thiscannot be accomplished by the use of a stick manually manipulatedthrough the opening in therwindow.

It is, of course, understood that should a different or larger amount ofopening be desired, the 'base will be accordingly shifted furtherfrom ornearer tothe junction of the sashes.

Should it be desired to permit free passage of the sashes 25 and 27, oneby the other, I rotate the abutment member 24 by engagement with thehandle 23, to withdraw its shank portion 21 from the base member 10,leaving the same threadedly engaging ythe mounting member 16,

thus permitting the mounting member vto be swung about its hinge to theposition illustrated in Figs. 3 and 4, whereby the sash 2'7 may be movedfreely past the sash 25 or vice versa, leaving the windows entirelyunobstructed and free to move as if the device were removed from itsposition.

In describing the position of the device, as

being placed onthe upper sash, I have assumed that the lower sash willslide along the face of the upper sash onwhich face the abutment memberis mounted. It will also be understood that in some cases, instead ofswinging the mounting member and the abutment member therewith, I maycompletely remove the abutment member 22 by a further withdrawingrotation of the abutment member to completely'remove it from themounting member.

' The foregoing description is directed solely towards the constructionillustrated, but I desire it vto be understood that I reserve theprivilege of resorting to all the mechanical changes to which Vthedevice is` susceptible, the invention being defined and limited only bythe terms of the appended claims.

I claim: n

1. A locking device for a window having sliding sashes comprising a basemember provided with a threaded opening therein a mounting member hingedto said base and having an opening therein, an abutment member lhaving athreaded portion rotatably engaging said mounting member and threadinglyengaging said base member whereby it may be detached from said basemember by rotation thereof to swing with said mounting member out ofworking position.

2. A locking device fora'window having sliding sashes comprising a basemember provided with a threaded opening therein, a mounting memberhinged to said base and having a threaded opening, an abutment memberhaving a threaded portion threadingly engaging said mounting member andthreadingly engaging said base member whereby it may be detached fromsaid base member by rotation thereof to swing with said mounting memberout of working position.

3. A locking device for a window having sliding sashes comprising a basemember having a threaded opening therein, a mounting member hinged tosaid base and having an opening therein, an abutment member having athreaded portion rotatably engaging said mounting member and threadinglyengaging said base member wherebyl it may be detached from said basemember by rotation thereof to swing with said mounting member out ofworking position, said abutment member being provided with a handleportion having recesses therein for rotation of the same.

4. A locking device for a window having sliding sashes comprising a basemember to be secured to one sash of a window, a mounting member hingedto said base member, said members having threaded openings aligning whenthe mounting member is in engagement with said body, an abutment memberhaving a threaded shank to enter said threaded openings for securing themounting and base members together and itself in the path of movement ofthe other sash of the window, said abutment member being rotatable towithdraw it from the threaded opening in'said base member and cause itto be carried wholly by the mounting member whereby it may be swung onits hinge to remove the abutment member from the path of movement of thesaid other sash.

5. A locking device for a window having sashes comprising a base memberhaving a face recess therein to be secured to one sash of a window, amounting member tting said recess and hinged to said base member, saidmembers having threaded openings aligning when the mounting member is insaid recess, an abutment member having a threaded shank to enter saidthreaded openings for securing the mounting and base members togetherand itself in the path of movement of the other sash of the window saidabutment member being rotatable to withdraw it from the threaded openingin said base member and cause it to be carried wholly by the mountingmember whereby it may be swung on its hinge to remove the abutmentmember from the path of movement of the said other sash.
